Old age is not normally associated with innovativeness and technical prowess. To the contrary, when treating age as a distinct category, policy makers, innovation scholars, and companies typically regard younger people as drivers of innovation, and the early adoption of new technology. In this paper, we critically investigate this link between age, ineptness, and technology adoption using a case study of the diffusion of electric bikes in the Netherlands. We demonstrate how, during the first wave of e-bike acceptance, old age was constructed as an arena in which important learning processes took place, and where older persons became early adopters of e-bikes. Theoretically, this paper speaks critically to the prolific literature on innovation diffusion and its treatment of adopter categories as generic concepts. Using age as a central dimension, our research highlights the situated and constructed nature of adopter categories, and thus challenges age-based assumptions about innovation and technology use by younger and older persons. These insights about what we term the rejuvenation of e-bikes help us rectify existing biases of older persons as an inherently problematic group of technology users.

This article examines how the authorization of scientific discourses in the US Endangered Species Act (ESA) of 1973 has influenced the ways people make claims about culturally significant animals. In it, I focus on struggles over the management of two endangered fish species among a federally recognized Native American tribe, state resource managers, and other actors. I discuss how the requirements of the ESA, namely that decisions regarding the protection of endangered species must be made based “solely on the basis of the best scientific…data available,” have pushed people to reframe their cultural claims about the environment as scientific claims in order to gain legal authority. I argue that these animals span the social worlds of indigenous hunters and fishers, regulators, and ecological scientists. As such, they offer the opportunity to interrogate the relationships among ways of knowing the environment. I suggest that strict divisions among “types” of knowledge as well as hard-and-fast bonds between groups and “their” knowledge become problematic. Instead, people assemble eclectic articulations of knowledge to make the most authoritative claim possible in a given context, contradicting the assumption that certain people know the world only, or primarily, in a particular way.
